There are many cases where the door closeer's cap screw is naturally lost because the lodgings are for more than 20 years, and confirmation is made when leaving the house. The size is just right, well stopped and very good.

We used M6 stainless steel for the mounting of the monkey's carrier.
I could also install the Phillips screwdriver without slipping, I think that the quality is also good and durable.
Regarding the length (mm), it seems to be the whole length from the head (heaven), not the length of the screw from under the neck.
Dimensions were difficult to understand, so be careful when ordering.
So ☆ I made four, I look forward to the improvement of the display method.

In the m6 class, the seat surface (dish surface) is wide and steady so that it can be held stably. If you are even seated, the surface will become flat so there is no worry about being caught. However, this type of screw, unlike a train or a train, because the way to measure the length of the screw is different, the screw part will be shorter than the same size of the other screws (below the seat).
